If you mean: 7x+91 then it can be factored to 7(x+13)
5x
The GCF is 6.
The GCF is 10.
The GCF is 3x3y2.
3x
3(2x + 1)

4(a+5b)
That factors to (m + n)(r + s) The GCF is 1.
The greatest common factor (GCF) is 4.
If you mean: 7x+91 then it can be factored to 7(x+13)

The greatest common factor of 12xy2 + 6x is 6x. The greatest common factor of 12 and 6 is 6, and the greatest common factor of xy2 and x is x. If you took 6x out of both factors, the end result would be 2y2+1
